  org.apache.tapestry5.internal.services.ContextPathEncoderImpl

All Implemented Interfaces:

ContextPathEncoder

public class ContextPathEncoderImpl
extends Object
implements ContextPathEncoder

Constructor Summary

ContextPathEncoderImpl(ContextValueEncoder valueEncoder, URLEncoder urlEncoder, TypeCoercer typeCoercer)

Method Summary

EventContext	decodePath(String path) Inverse of ContextPathEncoder.encodeIntoPath(Object[]); the path is split into strings, and the string are decoded and constructed into an EventContext.
String	encodeIntoPath(EventContext context) Encodes the context into a string.
String	encodeIntoPath(Object[] context) Encodes the context values into a path string.
String	encodeValue(Object value) Encodes a single value via the ContextValueEncoder service, returning the resulting string.

ContextPathEncoderImpl

public ContextPathEncoderImpl(ContextValueEncoder valueEncoder,
                              URLEncoder urlEncoder,

Method Detail

encodeValue

public String encodeValue(Object value)

Description copied from interface: ContextPathEncoder

Encodes a single value via the ContextValueEncoder service, returning the resulting string. Even null is encoded, as per URLEncoder.encode(String).

Specified by:

encodeValue in interface ContextPathEncoder

encodeIntoPath

public String encodeIntoPath(Object[] context)

Description copied from interface: ContextPathEncoder

Encodes the context values into a path string. Each context value (if non-null) is first value encoded into a string via the ContextValueEncoder service. Those values are then encoded, via URLEncoder.encode(String) into URL-safe strings. The URL-safe strings are then concatenated together, separated with "/" characters.

Specified by:

encodeIntoPath in interface ContextPathEncoder

Parameters:

context - an array of objects to encode as the context (may be null)

Returns:

the path-encoded context, or the blank string if the context is empty

encodeIntoPath

public String encodeIntoPath(EventContext context)

Description copied from interface: ContextPathEncoder

Encodes the context into a string. Returns the empty string if the context is empty.

Specified by:

encodeIntoPath in interface ContextPathEncoder

Parameters:

context - to encode

Returns:

encoded values separated by "/" characters, or the empty string

decodePath

public EventContext decodePath(String path)

Description copied from interface: ContextPathEncoder

Inverse of ContextPathEncoder.encodeIntoPath(Object[]); the path is split into strings, and the string are decoded and constructed into an EventContext.

Specified by:

decodePath in interface ContextPathEncoder

Parameters:

path - to decode, possibly empty or null

Returns:

corresponding event context
